    1995 Chevy k1500 5.7/350. Can't get rid of the positive camber

    1995 Chevy k1500 5.7/350. Completely stock front end/suspension, I believe the tires are slightly larger than stock. A good bit of positive camber on both sides, adjusted the 4 camber bolts on both sides all the way to pull the tops of the tires in, helped some but they are still very much out...

    1995 k1500, 5.7/350. Backfires through intake

    I see. Unfortunately, it does look like I've already got a heated sensor, based off of it having 3 wires. I do have a buddy that has a scanner for obd-I. I'll have him hook it up to see how it's looking. Do you think it could possibly be a timing issue? Thanks

    1995 k1500, 5.7/350. Backfires through intake

    The O2 sensor is actually installed on the exaust pipe, right past the header. I'm not sure if it was a heated unit or not, I cannot recall. I did buy mine from autozone, but I can't remember which one it was.

    1995 k1500, 5.7/350. Backfires through intake

    I really appreciate all of the information. Where could I get an adjustable fuel pressure regulator at? I searched for a bit but I couldn't seem to find one anywhere. Also, I'm not familiar with the spring your referring to. How do those work? Is it the one in the fuel pressure regulator? Thanks...

    1995 k1500, 5.7/350. Backfires through intake

    I'm not sure about the fuel pressure. Is there a port to check it on the 95 350s? From what I understand, the only way to really check it is to tap into the main line somewhere. Is there a way to adjust the fuel pressure regulator on a tbi? Forgot to mention that it was in fact tbi.

    1995 k1500, 5.7/350. Backfires through intake

    Replaced O2 sensor, MAP sensor, EGR valve, plugs, wires, distributer cap, TPS, IACV, knock sensor, and others within 20,000 miles from now. Also have checked with break clean for vacume leaks, couldn't find any. Are there any common hidden ones I should know about? Thought that may be helpful...

    1995 k1500, 5.7/350. Backfires through intake

    1995 k1500, 5.7/350, long tube headers, true duals straight piped with resonators, bypassed intake silencer and added salad bowl intake spacer. When running k&n air filter, seems to be getting too much air and backfires through the intake. Is there any way without having to tune ecu, to get the...

    EGR Delete - Will I benefit?

    In order to bypass the egr valve on a 95 k1500 tbi, could I simply unplug the egr purge valve wire harness and plug the hoses? It does make a difference, but I'm not sure if the egr valve is open or closed by default, without any instructions from the ecu. Thanks.

    Air intake through passenger fender?

    That's correct. Thank you, that does make sense. That's good to know. I'm fairly new to actual custom work, so that's why I'm here.

    Air intake through passenger fender?

    That is another interesting idea, though my apologies, I meant to say the inner fender, not actually through the body of the truck. There, I don't believe the wind would affect it much, seeing as the front of the truck would be covering it.

    Air intake through passenger fender?

    No, not quite. It would be a hole right through the passenger fender, with the end of the intake being pretty much right above the tire. Pretty much a straight shot from where the tube exits the air cleaner, to a hole in the fender, to eliminate any restrictions by not having much of any turns...

    Air intake through passenger fender?

    I see, just looking for a fairly easy way to get some hp gains, even if it's small. It's pretty much stock, just got some long tube headers on it.

    Air intake through passenger fender?

    I appreciate the reply. Would it not make a difference to take out all of the turns and restrictions that the original routing has going through the headlight, by instead going through the fender, directly beside the wheel?

    Air intake through passenger fender?

    While I was looking at modifying my 1995 chevy k1500 350's air intake to be more efficient while still remaining as a true cold air intake, I came across an interesting idea. If the intake was ran from the factory air cleaner, and through sealed tubing all the way across the engine bay like...
